实现信号的采样与恢复m文件（在matlab中实现）(Signal sampling and recovery m file (in Matlab))

语音信号的lpc分析，该程序实现了与语音预测器的阶数与预测残差能量的关系(The speech signal LPC analysis, the program with the order of the prediction residual energy of the speech predictor)

一个非常好用的国外牛人写的kalman滤波程序，(kfdemo.m is a Matlab script file to run a demonstration of the Bayesian Kalman filter. It loads file kfdemo.mat (saved as version 4 so that it will read in either v4 or v5 Matlab).The other files are called by kf.m (the Kalman filter) or included as they may be useful. Normalis.m normalises data to zero-mean, unit variance along components. I always do this before any further analysis.)

参考国外网站资料，自己实现的海宁窗滤波函数。滤波测试图像为matlab自带的cameraman.tif图片。(Hanning filter program in Matlab)

matlab中编写的一个计算PI参数的程序，可以自动整定控制系统的PID参数(PID controller caculate)

file contains a simulink modoel of inverter

说明：  BP算法是应用最广泛的神经网络算法，常用于预测，得到了很好的效果(BP algorithm is the most widely used neural network algorithm, commonly used in forecasting, we get good results)

Plot the Mathieu Beam and its phase and a cut in the graph. Put all archives in a same folder and run mthuwave file.

根据D.C.CHU提出的计算CAZAC序列的算法，计算出CHU序列的matlab程序。包括自相关函数，FFT变换后的CHU序列，以及CAZAC序列的一些特性，还提供D.C.CHU的算法原文(According to the calculation made by CAZAC sequence DCCHU algorithm to calculate the CHU sequence matlab program. Including the self-correlation function, FFT transformed CHU sequence, as well as some of the characteristics CAZAC sequence)
